Wherein the first transport pipe 101 is fixed on column 102, it can be along with swivel coupling 103 axially revolution together in pivoting support 105, and the second transport pipe 106 is in the outside of column 102, when column 102 turns round action, due to the second transport pipe 106 impeding externally, its angle of revolution maximum reaches 270 °, and the angle of revolution is limited, makes troubles for the use of hoist.
The model utility content
The applicant is restricted for above-mentioned existing production technology center pillar angle of revolution, uses the shortcomings such as trouble, and another kind of lose-lose oil pipe crane rotation joint is provided, thereby can realize easily 360 ° of revolutions of column, impede without any, stability of rotation is reliable, uses flexibly.
The technological scheme that the utility model adopts is as follows:
A kind of lose-lose oil pipe crane rotation joint, comprise base, described base top is equipped with column, described column bottom is provided with boss, be positioned at the boss place and by bolt, solid of rotation be installed, described solid of rotation inside is divided into the first oil transportation chamber and the second oil transportation chamber, is positioned at the solid of rotation outside and by seal arrangement, housing is installed; Be positioned at the column top and be separately installed with the first transport pipe and the second transport pipe, described the first transport pipe is communicated with the first oil transportation chamber, and described the second transport pipe is communicated with the second oil transportation chamber; Be positioned at the first oil transportation chamber one side and have the second opening, be provided with the second outlet on the housing corresponding with the second opening, described the second outlet connects the second ell; A side that is positioned at the second oil transportation chamber has the first opening, is provided with the first outlet on the housing corresponding with the first opening, and described the first outlet connects the first ell.
As further improvement in the technical proposal:
By lining and seal ring holder housing, described housing is fixed on base respectively in the outside of described solid of rotation.
The beneficial effects of the utility model are as follows:
The utility model is rational in infrastructure, and is easy and simple to handle, transport pipe in outside the second transport pipe and hoist realized that sound is connected, thereby realize 360 ° of revolutions of lose-lose oil pipe hoist.Its smooth running is reliable, uses flexibly, can be widely used in embedded transport pipe hoist.
